detailed description

The technical solution of the present utility model will be further elaborated below in conjunction with the accompanying drawings and specific embodiments.

Referring to the foldable stroller shown in Fig. 1 to Fig. 6, it includes a foldable vehicle frame and a foldable seat frame arranged on the vehicle frame.

The vehicle frame includes a front bracket 1, a rear bracket 2, a handle bar 4, a push rod 3, a side stay bar 5 and a seat post 6, wherein the upper part of the front bracket 1 is pivotally connected with the upper part of the rear bracket 2; Extending in the direction, the front pivot of the armrest bar 4 is connected to the upper part of the front bracket 1 or the upper part of the rear bracket 2, and the rear part of the armrest bar 4 is pivotally connected to the push rod 3. Specifically, in this embodiment, the front part of the handrail bar 4, the upper part of the front bracket 1 and the upper part of the rear bracket 2 are pivotally connected through the same rotating shaft; the push rod 3 includes a lower push rod 31 and an upper push rod 32, and the upper push rod 32 The bottom of the push rod 32 is pivotally connected to the upper part of the lower push rod 31 so as to be relatively flipped and folded. The rear portion of the armrest bar 4 is pivotally connected to the lower push rod 31; The upper part of the lower push rod 31 is pivotally connected to the lower part, and the lower part of the side stay 5 is pivotally connected to the rear bracket 2; the seat post 6 extends along the front and rear direction, and the front part of the seat post 6 is pivotally connected to the front bracket 1 Above, the rear of the seat post 6 is pivotally connected to the side stay 5 . In this embodiment, the armrest bar 4 is gradually tilted up from front to back to form an arc, which is not only beneficial to the arrangement of the bars, but also makes the overall frame of the vehicle have a beautiful arc and beautiful appearance.

The stroller also includes a frame lock (not shown) for locking the frame in the unfolded state. When the vehicle frame is folded, the upper push rod 32 turns back and folds relative to the lower push rod 31, and the upper push rod 32 and the lower push rod 31 go down and drive the rear part of the handrail rod 4 to go down, and at the same time make the side brace 5 relative to the rear bracket 2 Flip backward and drive the rear part of seat post 6 to turn down, so that front support 1, rear support 2, side stay 5, seat post 6, armrest bar 4, lower push rod 31, upper push rod 32 are gathered together.

The seat frame includes an upper wall rod 8, a lower wall rod 9, and a connecting rod 7, wherein the bottom of the upper wall rod 8 is pivotally connected with the upper part of the lower wall rod 9 and the two are framed when unfolded, and the connecting rod One end of the connecting rod 7 is pivotally connected to at least one of the upper wall rod 8 and the lower wall rod 9 , and the other end of the connecting rod 7 is connected to the handrail rod 4 . When the stroller needs to be folded, the seat frame can be folded before the frame is folded: first, the lower wall rod 9 is turned up so that it is rotated and folded relative to the upper wall rod 8, and then the frame is folded , the upper wall rod 8 and the lower wall rod 9 are folded backward relative to the connecting rod 7 to the rear of the vehicle frame.

In this embodiment, the lower part of the upper wall rod 8, the upper part of the lower wall rod 9 and the upper end of the connecting rod 7 are pivotally connected by the same rotating shaft, and the seat frame is provided with a seat frame for locking it in the unfolded state. As shown in FIG. 2 , the locking member 10 is arranged between the lower part of the upper wall rod 8 , the upper part of the lower wall rod 9 and the upper part of the connecting rod 7 for locking the three.

Referring to the accompanying drawings, in this embodiment, in order to make the structure of the folded cart more compact, the lower part of the connecting rod 7 can be slidably connected to the handle rod 4 along the handle rod 4, and the connecting rod 7 and the handle rod 4 is also provided with the seat pocket installation lock (not shown) that is used to lock the two to lock the seat pocket frame on the vehicle frame. Specifically, a chute 4a extending along the length direction of the armrest bar 4 is opened, and a sliding part is provided on the lower part of the connecting rod 7, and the sliding part is slidably arranged in the chute 4a. Here, the sliding member adopts a sliding pin 7a with one end fixed on the lower part of the connecting rod 7, and the other end of the sliding pin 7a is rotatably inserted in the sliding groove 4a. In this way, when the cart is folded, the lower part of the connecting rod 7 slides forward along the armrest rod 4, and at the same time the connecting rod 7 turns backwards with the rotation of the armrest rod 4, so that the upper surrounding rod 8 and the lower surrounding rod 9 are tightly folded into the cart. The rear of the frame, and close together with the upper push rod 32 and the lower push rod 31.

Of course, the lower end of the connecting rod 7 can also be slidably and rotatably connected with the handrail bar 4, so that the rods on the seat frame can be closely approached to the rear of the vehicle frame when the vehicle frame is folded, but The structure of the seat pocket installation lock between the lower end of the connecting rod 7 and the handle bar 4 will be more complicated than that in this embodiment.

To sum up, when the foldable stroller is in the unfolded state, the seat frame is locked on the vehicle frame and is in the unfolded state for riding, as shown in Fig. 1 and Fig. 2 . When the cart needs to be folded, first turn the lower wall bar 9 up and draw it in relative to the upper wall bar 8, and then turn the upper push rod 32 back after unlocking the vehicle frame to make the push rod 3 go down as a whole. The rods are relatively rotated and gradually gathered together, as shown in Fig. 3 and Fig. 4 . During the folding process of the vehicle frame, the connecting rod 7 slides forward along the handle bar 4 and rotates together with the handle bar 4 at the same time, and the upper wall rod 8 and the lower wall rod 9 are gradually turned backward relative to the connecting rod 7 . Finally, all the rods on the vehicle frame are tightly gathered together, and the upper surrounding rod 8 and the lower surrounding rod 9 are also tightly gathered together on the rear side of the vehicle frame and close together with the upper push rod 32 and the lower push rod 31 . The folded cart has a very compact structure, takes up little space, and the whole cart is light and compact, which brings convenience to users for daily carrying and storage.

The above-mentioned embodiments are only to illustrate the technical conception and characteristics of the present utility model, and its purpose is to allow those familiar with this technology to understand the content of the utility model and implement it accordingly, and not to limit the protection scope of the utility model. All equivalent changes or modifications made according to the spirit of the utility model shall fall within the protection scope of the utility model.
